Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed September 18,1905. Serial No. 279,015.

To all whom, it may concern:

Be it known that I, J miles J. GREEN, a citizen of the United States of America,and ares dent of Bremen, county of I-Iaralson, State of Georgia, have invented certain new and use ful Improvements in Cultivators,of which the following is a full and clear specification, reference being had to the accompanying drawings, in which? Figure 1 is a perspective. view of my improved cultivator; Fig. 2, a side elevation thereof; Fig. 3, a plan view, and Figs. 4, 5, and 6 detailed perspective views, of various forms of shovels that may be used with my cultivator.

The object of this invention is to provide simple means for regulating the depth of cultivation and for convenience in transporting the machine from place to place, as more fully hereinafter set forth. To the accomplishment of this object and such others as may hereinafter appear, the invention consists of the parts and combination of parts hereinafter fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout the several views.

Referring to the drawings annexed by reference characters, the letter A designates the main beam, (1 and a the teeth-carrying beams, which are attached at their inner ends to the main beam and inclined outwardly and baclnvardly therefrom, the spring-teeth B being bolted down to these beams. The beams on each side are parallel, and the rear one of each pair is notched or grooved for the reception of the shanks of the teeth B, and the shanks are held in position by means of supplemental beams a bolted down to the beams a. In this way a very rigid wellbraced structure is provided,.the shanks of the teeth themselves serving as means of bracing the beams. Suitable shovels H are attached to the working ends of the springteeth, and for different kinds of work these shovels may be interchanged for other types, as shown at J, K, and L in Figs. 4, 5, and 6.

Attached to the opposite sides of the forward end of the beam A is a pair of upright bars F, these bars being attached adjustably to the beam by means of a clamp consisting of the bolts f 2 and the connecting-links The lower ends of these bars f are bent outwardly in opposite directions, and to each of these outward-projecting ends is bolted the upper bent or folded end 9 of a spring-standard G, carrying a wheel 9 at its lower end.

A pair ofwheels 0, similar to the forward pair of wheels 9, is mounted in the rear of the outermost teeth. Each of these wheels 0 is journaled in the depending bifurcated end of a flat spring-support C, which curves upwardly and forwardly over the tooth and is pivotally connected by a loop I) to the shank of the tooth at a point betweenthe beams a and a. The wheel 0 is elevated and depressed by means of a sliding loop d, which embraces the body of the tooth at its curved portion, and the spring-blade C, and is pivotally connected to a flat spring D,which also extends forward and is pivotally attached to the loop (Z. To slide the loop (1 up and down radially, the operating spring-rod D is provided with arearward-extending handle E. It will be observed that the binding action on the loop (1 caused by the tendency of the Wheel 0 to rise will lock the spring-support C in its adjusted position. Sliding the loop (1 upward and downward releases or frees more or less of the spring esupport C and in that way permits the wheel 0 to have a Wider range of movement vertically, thereby allowing it to rise and fall to a greater or less extent by pressure upon the ground.

When it is desired to transport the machine from the field, the loops d are pressed down as far as possible, thereby bringing the wheels 0 closer to the teeth and elevating the shovels from out of contact with the ground. It will be observed that while the apparatus is working in the field the spring-supported wheels serve to resiliently support the machine, and thereby regulate the depth of cultivation and contributing to ease of movement over the ground.

lVhat I claim, and desire to secure by Letters Patent, is-

1. In combination with a main beam, a pair of rigid parallel beams extending outwardly therefrom on each side, the rear beam being grooved across its upper side, springteeth having their shanks bolted to the forward beams and lying in the grooves in the rear beams, and supplemental beams a bolted down on top of the rear beams, thereby rigidly confining the teeth in said grooves for the purpose set forth.

2. In combination with a frame carrying spring cultivating-teeth, of a series of springsupported wheels attached to the frame and adapted to bear upon the ground, the front wheels being supported on the frame and the rear wheels on the resilient portions of the teeth.

3. In combination with a cultivator-frame carrying a series of cultivator-teeth, of one or more ground-engaging wheels at the forward end of the frame, and a pair of resilientlysupported wheels at the rear of the teeth, and supported on the teeth.

4. 'In combination with a cultivator-frame carrying a series of cultivator-teeth, of one or more ground-engaging wheels at the forward end of the frame, a pair of resiliently-supported wheels at the rear of the teeth and supported thereon, and means for vertically adjusting the said rear wheels.

5. In combination with a frame carrying a series of spring cultivator-teeth, a resilientlysupported Wheel on the frame forward of the teeth, and a pair of resiliently-supported Wheels atthe rear of the teeth, and means for vertically adjusting these wheels, said means as well as the resilient supports of the wheels being supported on the teeth.

6. In a cultivator the combination of a frame carrying a series of cultivator-teeth having curved resilient body portions, a spring-supported Wheel or wheels on the frame in front of the teeth, curved resilient bars C depending behind the teeth and each carrying a groundengaging wheel, and means for vertically adjusting and locking the free Wheel-carrying ends of these resilient ars.

7. In a cultivator carrying a series of curved springteeth,a ground-engaging wheel or wheels at the front of the frame, and a pair of ground-engaging Wheels at the rear of the teeth one wheel being arranged at each side of the machine and each wheel being carried by a resilient bar extending rearwardly and downwardly behind the adjacent tooth, and means for vertically swinging the wheel-carrying ends of these resilient bars, for the pur pose set forth.

8. A cultivator comprising a frame carrying a series of curved spring-teeth, a front wheel or wheels, a pair of ground-engaging wheels behind the teeth and means for supporting them one at each side of the frame, and means for vertically adjusting these wheels, these adjusting means embodying a pair of rearwardly-extending handles.

9. In a cultivator the combination of a frame carrying a series of curved springteeth, of a ground-engaging wheel or Wheels at the forward end of the frame and a pair of ground-engaging wheels behind the teeth, a supporting-bar for each wheel pivoted at its forward end and curving down behind the adjacent tooth, and means embodying a rearwardly-extending handle for vertically adj usting the wheel-carrying end of each of said bars.

10. A cultivator comprising a frame carrying a series of spring-teeth, a ground-engaging wheel or wheels at the front end of the machine and a pair of ground-engaging wheels at the rear of the machine, each of these wheels being supported by a rearwardly and downwardly extending bar lying behind one of the cultivatorteeth, an adjusting and locking loop embracing said bar and the shank of the adjacent tooth, and

means for adjusting this loop for the purpose set forth.

11. In a cultivator the combination of a frame carrying a series of curved springteeth, of a supporting wheel or wheels at the forward end of the frame and a pair of groundengaging wheels at the rear of the teeth, each wheel being" supported on a curved resilient bar pivotally supported at its forward end,

.means for vertically adjusting the free rear,

end of this bar, said means embodying a slidable loop engaging said bar and the adjacent tooth-shank, a bar carrying this loop at its rear end, and a handle connected to this lat ter bar, substantially as set forth.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 15th day of September, 1905.

JAMES J. GREEN.
